What is an AC generator

There are two types of generator or dynamo.
Both turn rotational energy into electrical energy.

An AC generator requires a coil to
cut across the force lines of a magnetic field.
This coil is attached to two slip rings,
which deliver the current to and from the load
destination,
thus completing the circuit.
Alternating current generators are often called alternators.
1. coil inside a magnet.

2. dynamo

This type involves rotating a magnet inside a coil
(like a dynamo found on a bicycle).
